Mobility Model for Vehicular Ad Hoc Networks: A Survey and Taxonomy

Abstract

Vehicular Ad-hoc Networks (VANETs) have been recently attracting an increasing attention from both research and industry communities. However, due to the large number of available models claiming to be adapted to vehicular traffic, and also due to their different and somehow incomparable features,understanding their true characteristics, their degree of realism with respect to vehicular mobility, and real capabilities is a hard task. In this survey, first ,a framework that proposes a guideline for the generation of vehicular mobility models is discussed. Then, the different approaches chosen by the community for the development of vehicular mobility models and their interactions with network simulators are illustrated .Finally, a proposal for an overview and taxonomy of a large range of mobility models available for vehicular ad hoc networks is formulated. The objective is to provide with a guideline to easily understand and objectively compare the different models, and eventually identify the one required for their needs. One of the fastest growing domain of interest in VANETs is safety, where communications are exchanged in order to improve the driver’s responsiveness and safety in case of road incidents.
